Can I change out the yoke in my 12 bolt without changing the pinion preload or anything else important? I just had my gears done, 3.07 to 4.10, and Detroit Locker rear / Truetrac front installed. The shop that did them told me when I picked up the Jimmy, "Your rear yoke has a broken off bolt that someone has tried to repair". I wish they had just called me so I could have had them to fix it. The bolt broke off , was drilled and tapped one size bigger (3/8-20) with about 1/2 in. of thread, and a short Allen bolt was installed. With it having straps not u-bolts this sucks. Is there a 12 bolt yoke that is u-bolt not straps? I guess I need to put a "beg" in the parts needed forum.
